This is the name of the southernmost neighbourhood on the Lido, ruled in the Renaissance by the Pisani family. Its parish church is Santa Maria Assunta and is currently the site of Dingo, Venice's stray cat sanctuary.
It's also the name of one of the three deep shipping channels into the lagoon (mostly used for cargo ships en route to Marghera).
Confusingly it's also the name of a now submerged island east of the Lido (at least that's what most people think) that served as one of the first capitals of Venice, under the reign of second doge, Theodatus (742-755), a status that endured until the capital was moved to the greater safety of the Rialto in 811.
